coding and hosting

host ngrok 1.x on GCE first

[changtimwu]

official ngrok service is very slow alternatives

• self ngrok hosting docker http://blog.sequenceiq.com/blog/2014/10/09/ngrok-docker/
• another implementation https://github.com/mmatczuk/go-http-tunnel

In GCE menu, choose VM region asia-east1 which is physically in Taiwan.

go-tunnel takes port 5223 by default we open port on GCE in this way https://stackoverflow.com/questions/21065922/how-to-open-a-specific-port-such-as-9090-in-google-compute-engine

self-hosting go-tunnel works great. something might be different than the ngrok service.

• when redirecting TCP, client port is specified instead of random assigned.
• when redirecting HTTP, hostname is specified instead of random assigned.

we may need STUN/TURN server

• https://github.com/coturn/coturn webrtc issues on safari

twilio NTS would be another option. Great webrtc global solution. However, it regions doesn't include Taiwan. Here are its pricing.

valuable discussion about here webrtc and codecs

[changtimwu]

some open source IM implementation integrate webrtc for audio/video communication

• https://riot.im/app/#/home
